使用 cowsay 命令的 3 种有趣方式

大多数时候，终端是一个生产力的动力源。但是，终端的作用不止是命令和配置。在所有杰出的开源软件中，有些是 [为了好玩而写的][2]。我以前介绍过一些 [有趣的命令][3]，但这篇文章只讲一个：古老的 `cowsay` 命令。
|
|||
|
|
|
|||
|
|
`cowsay` 是一只可配置的会说话（或思考）的牛。它接受一个文本字符串，并输出一个牛说话的图形。下面是一头牛在说它喜欢 Linux：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
< I love Linux >
|
|||
|
|
--------------
|
|||
|
|
\ ^__^
|
|||
|
|
\ (oo)\_______
|
|||
|
|
(__)\ )\/\
|
|||
|
|
||----w |
|
|||
|
|
|| ||
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
要得到这个结果，我只需输入：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cowsay "I love Linux"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 在 Linux 上安装 cowsay
|
|||
|
|
|
|||
|
|
你可以用你的包管理器安装 `cowsay`。在 Debian、Mint、Elementary 和类似的发行版上：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ sudo apt install cowsay
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在 Fedora 上：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ sudo apt install cowsay-beefymiracle
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Cowsay 命令选项
|
|||
|
|
|
|||
|
|
`cowsay` 是一个简单又有点傻的应用。除了为你的终端机提供一些不同样式外，它并没有什么实际用途。例如，与其让一头普通的牛说一个有趣短语，你可以让一头长着古怪眼睛的牛说一个有趣的短语。输入：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cowsay -e @@ Hello
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
你会看到：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
< Hello >
|
|||
|
|
-------
|
|||
|
|
\ ^__^
|
|||
|
|
\ (@@)\_______
|
|||
|
|
(__)\ )\/\
|
|||
|
|
||----w |
|
|||
|
|
|| ||
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
或者你可以让它伸出舌头。输入：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cowsay -T U Hello
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
你会看到：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
< Hello >
|
|||
|
|
-------
|
|||
|
|
\ ^__^
|
|||
|
|
\ (oo)\_______
|
|||
|
|
(__)\ )\/\
|
|||
|
|
U ||----w |
|
|||
|
|
|| ||
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
更好的是，你可以将 `fortune` 命令与 `cowsay` 结合起来：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ fortune | cowsay
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
现在你有了一头特别睿智的牛：
|
|||
|
|
|
|||
|
|
```

### “结实的奇迹”
|
|||
|
|
|
|||
|
|
在 Fedora 上，有一个额外的 `cowsay` 选项，也是一个非官方的项目吉祥物。多年来，Fedora 安装程序一直在展示宣传开源贡献的幻灯片。因为它们是根据汽车电影院的插曲设计的，所以幻灯片中常见的卡通人物是拟人化的热狗。
|
|||
|
|
|
|||
|
|
为了与这个主题保持一致，你可以用 Fedora 版本的 `cowsay` 调用一个所谓的“<ruby>结实的奇迹<rt>beefy miracle</rt></ruby>”。（LCTT 译注：Fedora 17 的开发代号。）
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ cowsay -f beefymiracle Hello Fedora
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
你会得到一个非常傻的输出：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
< Hello Fedora >

|||

|
|||
|
|
|
|||
|
|
### 图形化的 cowsay
|
|||
|
|
|
|||
|
|
如果你发现自己需要用图形化的牛来传递信息，可以使用 `xcowsay` 命令。这是一个类似于 `cowsay` 的图形程序，它接受一个由用户输入的文本字符串，或从另一个应用（如 Fortune）输送过来的文本字符串。

### 有趣的 Linux 命令
|
|||
|
|
|
|||
|
|
虽然 `cowsay` 不是一个有用的命令，但它是一个有趣的命令，相当于你终端的桌面小工具。它很适合用来分散注意力和进行有趣的管道命令实验（尝试将 `ifconfig` 管道到 `cowsay`，或 `lsblk` 或 `mount`，或任何东西！）。如果你想让你的终端更有趣，试试 `cowsay`。
